6 - 20 GHz Distributed Amplifier
Port Configuration and Functions
Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | Ground | Housing or ground lug must be connected to a DC/RF ground potential with high thermal and electrical conductivity. |  |
| RF In | RF Input | This is the amplifier’s RF Input port. It is RF matched to 50 Ω and has built-in DC blocking capacitors. |  |
| RF Out | RF Output | This is the amplifier’s RF Output port. This port is RF matched to 50Ω and has built-in DC blocking capacitors. | |
| Vb | Positive Bias Pin | The V B pad provides a required positive bias which supplies the current mirror. A higher voltage results in a higher current draw through the VD port. This port should be set to +3V for normal operation. |  |
| Vd | Drain Supply Pin | The VD pin supplies DC voltage to the drain of the amplifier IC This pin is nominally set at +3V with the VD pads bonded together. |  |

Absolute Maximum Ratings
The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device
| Parameter | Maximum Rating | Unit |
|---|---|---|
| Bias Current (Ib) | 10 | mA |
| Bias Supply Voltage (Vb) | 4 | V |
| Drain Current (Id) (RF Applied) | 175 | mA |
| Drain Supply Voltage (Vd) | 4 | V |
| Maximum Operating Temperature for MTTF > 1E6 hours | 85 | °C |
| Maximum Storage Temperature | 125 | °C |
| Minimum Operating Temperature for MTTF > 1E6 hours | -40 | °C |
| Minimum Storage Temperature | -55 | °C |
| RF Power Handling | 15 | dBm |

Recommended Operating Conditions
The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications. Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.
